Trimble GCS900 on a Dozer with the Universal Total Station

The Trimble® GCS900 Grade Control System with the Trimble SPS930 or SPS730 Universal Total Station can be installed on dozers for a wide range of earthmoving applications. The Trimble GCS900 on a dozer with the ATS Construction Total Station is a full 3D control system that puts the site plan - design surfaces, grades and alignments - inside the cab.

Using the Trimble SPS930 or SPS730 Universal Total Station, the exact position, accurate cross slope, and heading of the blade is measured. This is especially advantageous for complex design surfaces such as super-elevation grading tasks.

The on-board computer uses this position information, and compares it to the design elevation to compute cut or fill to grade. This information displays on the Trimble CB430 screen- in plan, profile, cross-section view, or text. The cut/fill data is also used to drive the valves for automatic blade control. Additionally, the cut/fill data is passed to the GCS900 lightbars, providing additional visual guidance to the operator for up/down to grade and right/left to a defined alignment. The GCS900 on a dozer can be operated in either indicate or automatic mode.

The Trimble SPS930 or SPS730 Universal Total Station includes a total station, a license-free radio link and an active target mounted to the dozer blade. The total station uses active target technology to reliably lock onto and track the target. This unique feature eliminates false lock-ons, ensuring that the correct machine is being tracked. Additionally it has built-in "search intelligence" to quickly search for and find the target when lock is lost. The high up-date rate, low latency and synchronized angles and distance measurements capabilities make it perfect for dynamic applications.

The Trimble GCS900 on a dozer with the Trimble SPS930 or SPS730 Universal Total Station is ideal for contractors who need the flexibility to move from site to site frequently, work in confined spaces, or perform high-precision grading with their dozer. The total station allows contractors who operate independently or frequently move between projects to move both the dozer and the Trimble GCS900 Grade Control System from site to site quickly and easily. For jobs where GPS is not a viable technology, such as in urban canyons, heavily treed areas, or on job sites with numerous overhead obstructions such as overpasses, the total station offers a 3D grading solution.

Using the Trimble GCS900 with the Trimble SPS930 or SPS730 Universal Total Station on a dozer allows contractors to significantly improve their productivity and profitability.
